초록

It has been reported that when a drill ship is working in a stationary state, turbulent flow occurs inside the moon pool due to the inflow of ocean waves, which can seriously threaten work delays and worker safety. In this study, a computational fluid dynamics analysis of the internal flow of a drillship moon pool was carried out for various heights of the recess deck.
OpenFOAM, which is an open source library, was used for simulations. KCS was selected as the drill ship, and the recess deck heights were designed to be 0.0375 L, 0.0307 L, 0.0238 L, and 0.0169 L, respectively. The head wave was considered and the 5th–order Stokes wave was applied. By observing the change of free-surface flow inside the moon pool in each case, it is confirmed that the recess deck height affects the reduction of flow inside the moon pool. It is expected that the recess deck height derived from the results of this study can contribute to increasing the work efficiency and improving the safety of workers in the moon pool.
